1 edit | Why would someone want the whole HD-DVD disc? Even though I have a 20Mbps symmetrical connection and 3TB of storage I really don't see a point in downloading a 23-27GB HD-DVD disc. Its a waste of space, bandwidth, and time, so I agree with the AACS devs on that point. If you wanted the whole disc you might as well go out and buy it. Its is the same with DVD, not many people download the whole disc, but many more download dvd re-encodes. With the ultra-clean high bitrate sources of HD-DVD and Blu-ray they should make for some very nice DVD-5 or DVD-9 sized x264 re-encodes with minimal quality loss. In the near future sharing those HD-DVD x264 dvd sized re-encodes over P2P networks will probably become common and preferred over their HDTV-Captured brethren for the increase in quality. | |

| Compression will rue the day still divx and mpeg codecs can be ramped up to support hi-def capability with several gigabyte savings... here and there.. with virtually no (noticeable) loss, just hasn't really been invented yet, as there isn't a pressing need.. just give it 5 years.. | |

| They're right... to a point For some, downloading full HD (1080p) content is going
to be done just because they can do it. The AACS Developers'
claim sounds like a challenge that some with very high speed
connections will meet.
But the size of the files and the upload BW available to
most, as well as the high cost of media and the HDTVs to
view it on, will deter others from downloading full HD DVDs.
There are already some compressed HD format movies (h.264)
that don't eat up so much bandwidth, HD or removeable media
space - these are going to be more attractive than the 1080p
full HD content for a while.

| The Math I only skimmed through this thread, but it didn't look like anyone actually really calculated the time needed to download one of these movies.
Say you have 8000/768 from Comcast (I'll use this as I have had it before). You want to download an HDDVD, which is (up to) 30GB.
8000kbps = 1000KBps = 0.976MBps (max line speed)
30GB = 30720MB (size of disc)
30720MB X .976MB per second = 29983 seconds, or about 8 hours, 20 minutes to download.
So with an 8mbps connection, in theory, you can download an entire HDDVD overnight, while you sleep.
The only problem is, I've NEVER found ANYWHERE I could download any one single file that fast. The only way I was EVER able to max out my 8mbps connection was by downloading multiple files from multiple servers on IRC. (Yes, it was pirated content; not the point.) I couldn't even get a torrent with oodles of peers to max it out.
So with an 8mbps Comcast or 15mbps FiOS connection, you can download an HDDVD or Blu-Ray film in the time it used to take to download a CD's worth of mp3's on dial-up (that's how I started!). IF you can find a fast enough source.

| Re: The Math Like I said, the ONLY time I could ever max out my 8mbps Comcast connection was multiple downloads across multiple IRC servers. I couldn't max out my connection with Bearshare, Azureus, or FTP.
MAYBE if a HDDVD torrent is popular enough, you could max out that connection, but if an HDDVD torrent IS popular enough, I suspect the host site to be sued/shutdown for copyright BS.
IMHO, the best bet for one of these downloads would be IRC, but it certainly would NOT max out an 8mbps connection. And like you said, packet loss would screw an IRC download (at least using mIRC like I do).

| Imagine what will happen to regular divx these days So people are fairly satisfied with Divx movies. Imagine what will happen when the 50/10 pipes become more mainstream in the next 5-10 years as FIOS expands and AT&T trashes project slightspeed for a fiber connection. I mean the time period is short enough such that Divx is still acceptable. It isn't the difference between DVD and analog it is the difference between pretty good looking and stellar. Now take that 700MB movie and divide it by 50 Mbps. 2 minutes a movie anyone? 10 minutes a DVD? | |

| Re: Imagine what will happen to regular divx these days lol if you know where to go, you can max out your 100 mb fiber connection  so all this talk about how we don't have enough bandwidth... please.. nothing but bs. I somehow received an HD DVD movie in 6 hours and 30 minutes, it was 19 gb.  | |

Then you can just get the movie from Netflix, no need for downlaoding when Netflix still delivers the Sneakernet. | |
